The oldest air conditioner I have seen is in J Ward, the lunatic asylum. At the highest point in the old jail they used as a hospital is a fireplace. At the end of a vey hot day as the air cooled outside, they lit a fire in it and then closed the doors to the fire so it had to draw oxygen through vents that went to each cell. The hot air in the cell was removed and fresh, cool night air was drawn into the cell through the windows. The year this was built? 1858-1862.
The Roman’s would place large candles in the ceilings of their gathering halls to pull in fresh air to keep things cool. The concept has been around a long time.
Air conditioning is also part of how the movie industry fought Television. As TV was growing in the 40s and 50s the cinema needed something to get people back again, Anamorphic wide screen and color were one and AC was another. Because on a hot summer day you could now go see a movie in a cool room, Something you could not do at home back then(most people lacked an AC unit in that era). Of course once the movies became a hot day refuge we got the summer blockbuster.
Movie theaters being a refuge from hot days started back in the 30's, the theater John Dillinger was shot and killed walking out that night after a blistering hot July 22nd day in 1934 had written on its marquee "air condiiltioned theater". Theaters were the first public places to use air conditioning for human comfort, previous to that it was just used for commercial applications, like every other luxury during the 30's expansion was slow because of the depression, but after WW2 when the economy took off air conditioning for both businesses looking to draw in people and its use in residential homes skyrocketed. People went to theaters up to and throughout the 70's because that was basically the only way to see a movie, unless you wanted to wait over a year hoping a movie you wanted to see might come on television, it wasn't until cable television with its multiple channels that showed movies around the clock could you pretty much be guaranteed to see a movie at home, before that only the biggest movies would be picked up by the networks who only had a couple nights a week they'd show movies on, theatrical flops like Blade Runner and The Thing that later turned into classics never would have done that in the 70's, being played on heavy rotation on cable movie channels is what bailed them out, just a few years previous when a movies reputation was based entirely on how they performed in theaters and movies like that would be forgotten. Theaters pretty much had the market cornered when it came to seeing movies until the 80's, now it's even worse, with the advent of large flat screen televisions capable of showing movies in their correct format that turn your living room into practically a theater along with movie theaters closing in many small towns during the 2020 pandemic many people will just wait a couple months and watch a movie at home, the two multiplexes in my hometown closed in 2020 and I'm not about to drive 40 minutes down a toll road, $8 each way, just to go see a movie when I can watch it 2 months later in my living room that my TV practically turns into a theater, and I can pause it anytime I want.
One of the big early users of air-conditioners were tobacco factories in the southern US where the air-conditioners helped reduce tobacco dust and improved the quality of the products.
Before 1950 you didn't see many people in places like Flagstaff or Phoenix But the Rural Electrification Program and A/C made the southwest population grow out of control
I've always wondered how people survived in Florida back in the 1800's wearing those heavy wool clothes in all the layers that was the typical garb of the time, you see them in those pictures that date from back then and you can just imagine all the cases of heat stroke.
wow HOW ITERESTING, I sold paper to printers for 25 years and never knew this was the impetus for Air conditioning's creation. Although I had known that paper needed to acclimate for a couple of days in order to stabilize in the printer's warehouse/printing rooms.
To further explain how compressing a gas heats it and expanding a gas cools it down: Imagine a box full of tiny bouncing balls (because that's essentially what a gas is). Each ball has a velocity, and the average velocity is proportional to the temperature. Higher temperature, higher average velocity. When they bounce off the walls they remain at the same speed, but travel in a different direction. Now let's imagine we start to shrink the box, moving the walls inward. Think about one of those balls. When it hits the wall, the ball will have more speed after it bounces because the relative velocity between it and the wall is higher due to the wall's inward movement. Like hitting a tennis ball. Remember that the velocity of the balls is proportional to temperature, so by shrinking the box you've ended up increasing the speed of all the balls in it. The same holds true when the box expands, except instead of speeding up the balls they instead slow down.
My father was born in the 30’s and me in the late 80’s. He didn’t have ac put in our house until I was 15 or so years old. Still remember being miserably hot trying to sleep. As an adult I’m kinda fanatical about having ac to sleep but mostly anything else I’m very easy about. But man I hated that. Always sweating. 😂
The use of air conditioning in the textile industry was pioneered in Cramerton, North Carolina by Stuart Cramer, it is said that Willis Carrier was involved.
The coolest system I’ve seen (pun not intended) is in the Fox Theater in Atlanta, GA, but in 1929, the theater still uses its two old coal fired steam boilers, its original 1930’s carrier centrifuge chiller, air wash plenum, and 20 foot tall 50 hp electric blower. In the hot southern summers when the new system gets overwhelmed, the in-house engineer throws the switch to the original 30’s system and can cool down the entire theater in less than 15 minutes
Nice story, but misleading. Although Carrier is credited with the invention in the US, it is widely known throughout Europe that the original inventor was a brilliant French engineer named Pierre Conditionier
11:24 Now hold up, why show a smoke stack bellowing dark ass smoke when that's only 19% of America's energy production? Natural gas isn't clean, but it's not what you show pictured. Even coal isn't like what's pictured. How dare you! 😂
I believe split systems are actually slightly less efficient. Well build window units, if sealed well, are more efficient as the condensation from the evaporator is used to help cool the condense. However, split systems can also work as heat pumps saving energy in the winter where as window units generally can't.
@@pjamajones8304 Not sure what you are arguing but I am assuming you are talking about using a window AC unit as a heat pump? Yes, i am well aware that they do exist and have for a long time. However, if you look at my original post, I clearly says that they "generally can't". That doesn't state that there are none than can but most window units sold don't have the nessisary valves to act as a heat pump though some do. It just isn't that common for people to spend the extra money to get that feature and thus is rare.
On railroad passenger cars they had doors on the sides and they had huge blocks of ice they put in them. Then fans blow the air from the cabin across the ice to cool the cabin
You are correct, it is closer to 83%...but...the majority of it is hydroelectric due to all the rivers. It is worth noting that hydro power requires the building of dams, resevoirs, and accompanying significant changes to the environment to take advantage of (i.e effects on fish populations etc if unable to access water above the dam). And there is always the chance of a drought which would be particularly problematic with so much dependence on that type of power generation. Every type of power has advantages and disadvantages...
You can check all the energy generation in Brazil in real time here: www.ons.org.br/paginas/energia-agora/carga-e-geracao It is an official website of the national interconnected system that sends energy to all regions of the country.
What does the amount of renewable energy have to do with its efficiency? A Diesel generator is about 25-30% efficient and still I can easily power 100% of my home with one
@@beaversareinsane726 Great points. Dams are ecological nightmares and have turned into 'green' jackpots due to the credits and higher rates that are charged to power companies that can purchase this power to meet quotas. This has been happening all over remote parts of Canada for decades and the energy produced is mainly sold to US power companies. But if you look at wind & solar (which are not renewable at all, but always grab the 'renewable' attention), it is only 10% in Brazil - which is normal due to the high costs, low returns, and huge masses of land clearing and transmission lines necessary. 'Biomass' also accounts for 10% of 'renewable' sources in Brazil. Biomass is problematic because it includes burning a large umbrella of fuel sources including trees, garbage, ethanol, biodiesel, and peat. This encourages further destruction of rain forest areas in order to cut trees for fuel, mine peat, and plant larger crops of sugar cane (for ethanol production, a net-negative BTU source). As you stated, all sources of energy have pro & cons. But greenwashing is a real thing, and incentives lead to corruption and unintended consequences.
The most unsustainable gadget that humanity ever invented... I still wonder how American become so addicted to A/C...? Europe have the same climates and we don't use not even half of the A/C units Americans have...! I live in a hot southern country and I hate A/C, it even makes me sick in the Summer having to enter a space with A/C blasting cold air...! As I know in the entire of Europe only some Spaniards have the same A/C addiction, but it's more understandable due to their hot half-desert kind of climate... I Understand the "need" for A/C on hot climates but in the US it exists everywhere even in regions that never get really hot... But like in everything else America is the land of all the excess...!
It's the relative humidity combined with heat which causes the discomfort and the need for AC...In hot dry climates Evaporative coolers are much cheaper to run although can use a lot of water.
@johnunderwood239 someday I will post proven facts that the climate change is a fraud to fake ones from a rich country and give it to the poor countries. Please don't follow your herd of sheep over the cliff. BTW...do you really know where wind energy really originates from and how this negatively effects weather and climate? HINT: it was taught in high school at one time.
climate change isn't a theory. It's merely a measurement. A thermometer in the ocean. The ocean has been getting hotter every year. Good bye corral reefs.

I mean, it’s called the “stack effect” and is a completely different concept that people have known about (designed around anyways) since the 1700s.
They’ve known about it for thousands of years.
That's not the removal of heat energy, that's basic ventillation.

Amazing stuff. No such thing while growing up. Fans is what we used. And alot of trips to the beach. Now we can’t live without it.
Great research and look back into history. Thanks.
The other advantage of the modern ac is the flow can be changed, allowing it heat in winter.
Really nice job on the video. Well-written and researched. Thanks!

Grew up in Dallas in the 50’s. No AC until I was about 14. Up till then we didn’t know any better.

Good piece of history loved to learn about the vacuum cleaners
In WW2 US submarines were air conditioned, not for the crew but for the targeting computer and the radar.
Pretty sure pumping sea water through pipes doesn’t count.

On railroad passenger cars they had doors on the sides and they had huge blocks of ice they put in them. Then fans blow the air from the cabin across the ice to cool the cabin
The first residential air conditioner was installed in a home in Minneapolis, a city famous for cold weather. ??
Yes, the Midwest and Northeast of the US is cold in the winter, but hot in the summer.
